To recognize this diversity, a sectional classification system has been established. Power Operated Doors i
8、s one such section and this Standard is a result of the collective efforts of members of the Builders Hardware Manufacturers Association, Inc. who manufacture this product. The total Product Standards effort is, therefore, a collection of sections, each covering a specific category of items. Perform
9、ance tests and, where necessary, dimensional requirements have been established to ensure a degree of safety. There are no restrictions on design except for those dimensional requirements imposed for reasons of safety. This Standard is not intended to obstruct but rather to encourage the development
10、 of improved products, methods and materials. The BHMA recognizes that errors will be found, items will become obsolete, and new products, methods and materials will be developed. With this in mind, the Association plans to update, correct and revise these Standards on a regular basis. It shall also
11、 be the responsibility of manufacturers to request such appropriate revisions. -,-,- 4 TABLE OF CONTENTS 1. GENERAL.5 2. DEFINITIONS.5 3. REQUIREMENTS FOR SWINGING POWER ASSIST DOORS.6 4.

12、NSI/BHMA A156.19) .9 5 1. GENERAL 1.1 Requirements in this Standard apply only to swing door operators. The operator types are power assist, and low energy power operators, for pedestrian use, and some small vehicular use. It does not address doors, finish or hardware. The activation of all doors de
13、scribed in this standard requires a knowing act. Included are provisions intended to reduce the chance of user injury or entrapment. 1.2 Doors that require higher speeds, forces, shorter time delays, and activating sensing devices shall comply with ANSI/BHMA A156.10 for Power Operated Pedestrian Doo
14、rs and are not covered in A156.19. 1.3 This Standard does not attempt to assess any factors that exist with respect to custom design installations which are not required to meet the requirements of this Standard. 1.4 Unless otherwise specified, all references to time delay, opening speed and forces
15、in this standard, refer to the operator in the power mode as opposed to the manual mode. 1.5 Required dimensions are expressed in US units first and the SI (metric) equivalents given in parentheses are approximate. All values which do not carry specific tolerances or are not marked maximum or minimu
16、m shall have the following tolerances: Linear dimensions shall be 1/16 in (1.6 mm). Pounds or pound force shall be 5%. Angular measurements shall be 4 degrees. Voltage measurements shall be 5 percent. Temperature measurements shall be 4 degrees F (2 degrees C). 1.6 Compliance with the requirements o
17、f this standard shall be accomplished through factory settings or field adjustments as necessary. 1.7 Operators used on labeled fire door assemblies shall be listed or labeled by a nationally recognized independent testing laboratory, and be subject to a periodic in-plant follow-up service. Consult
18、the authority having jurisdiction for the appropriate fire test requirements. 2. DEFINITIONS 2.1 Knowing Act Consciously initiating the powered opening of a low-energy door using acceptable methods including: wall or jamb-mounted contact switches such as push plates; fixed non-contact switches; the
19、action of manual opening (pushing or pulling) a door; and controlled access devices such as keypads, card readers, and keyswitches. 2.2 Low Energy Power Operated Door A door with a power mechanism that opens the door upon receipt of a knowing act activating signal, does not generate more kinetic ene
20、rgy than specified in this Standard, and is closed by a power mechanism or by other means. 2.3 Power Assist Door A door with a power mechanism that activates by pushing or pulling the door, reducing the opening resistance of a self closing door to allow easier manual opening of the door. If the open
21、ing force on the door is released, the door shall come to a stop and either immediately begin to close, or begin to close after a predetermined time. 2.4 Push-Pull Activation A door where the user pushes or pulls a door equipped with a Low Energy Power Operator to activate a mechanism, causing the d
22、oor to go through a complete cycle of automatic opening, hold open time delay, and closing. 2.5 Small Vehicular Carts used to transport people or objects. -,-,- 6 3. REQUIREMENTS FOR POWER ASSIST DOORS 3.1 Activation Power assist doors shall operate only by pushing or pulling the door. An activating
23、 means is permitted to be used to put the door in the power assist mode. 3.2 Opening If the opening force on the door is released, the door shall come to a stop and either immediately begin to close or begin to close after a predetermined time. 3.3 Time Delay Not required. 3.4 Closing Doors shall cl
24、ose from 90 degrees to 10 degrees from closed, in 3 seconds or longer as required in Table I. Doors shall close from 10 degrees to fully closed in not less than 1.5 seconds. 3.5 Force and Kinetic Energy The force required to prevent a door from closing shall not exceed 15 lbf (67 N) measured 1 inch
25、(25 mm) from the latch edge of the door at any point in the closing cycle. Doors shall open with a manual force not to exceed 15 lbf (67 N) to release a latch if equipped with a latch, 30 lbf (133 N) to set the door in motion, and 15 lbf (67 N) to fully open the door. The forces shall be applied at
26、1 inch (25 mm) from the latch edge of the door. 3.6 Signage See Section 6 for signage. 4. REQUIREMENTS FOR LOW ENERGY POWER OPERATED DOORS 4.1 Activation The operator shall be activated by a knowing act. 4.2 Opening Doors shall open from closed to back check, or 80 degrees which ever occurs first, i
27、n 3 seconds or longer as required in Table I. Backcheck shall not occur before 60 degrees opening. Total opening time to 90 degrees shall be as in Table II. If the door opens more than 90 degrees, it shall continue at the same rate as backcheck speed. 4.3 Time Delay When powered open, the door shall
28、 remain at the fully open position for not less than 5 seconds. Exception: When push-pull activation is used, the door shall remain at the fully open position for not less than 3 seconds. 4.4 Closing Doors shall close from 90 degrees to 10 degrees in 3 seconds or longer as required in Table I. Doors
29、 shall close from 10 degrees to fully closed in not less than 1.5 seconds. 4.5 Force and Kinetic Energy The force required to prevent a stopped door from opening or closing shall not exceed 15 lbf (67 N) measured 1 inch (25 mm) from the latch edge of the door at any point during opening or closing.
30、The kinetic energy of a door in motion shall not exceed 1.25 lbf-ft (1.69 Nm). Table I provides minimum times for various widths and weights of doors for obtaining results complying with this kinetic energy. Doors shall open with a manual force not to exceed 15 lbf (67 N) to release a latch, if equi
31、pped with a latch, 30 lbf (133 N) to set the door in motion, and 15 lbf (67 N) to fully open the door. The forces shall be applied at 1 inch (25 mm) from the latch edge of the door. 4.6 Signage See Section 6 for signage. -,-,- 5. CYCLE TESTS 5.1 Low Energy Power Operated, and Power Assist doors shal
32、l be cycle tested for 300,000 cycles. 5.2 Use the widest and heaviest test specimen recommended for use by the manufacturer. Narrower or lighter doors of the same configurations shall then be considered to meet the cycle test requirements. 5.3 Use the requirements in Table I to determine opening and
33、 closing times. Open the door to a 90 + 5 degree open position and close the door to the 0 + 2 degree closed position using appropriate equipment. One opening and closing constitutes one cycle. In the case of Power Assist doors, use an actuator exerting an equivalent force equal to a 15 lbf (67 N) m
34、easured at 1 in (25 mm) from the latch edge of the door applied in the opening direction and allow the closing device furnished to close the door. 5.4 At the conclusion of the cycle test, the doors shall operate in accordance with requirements of Table I, and the actual opening and closing time shal
35、l be within -10 % to +20 % of their respective values at the commencement of the test.

Doors of other weights and widths can be calculated using the formula: T = D/133 in US Units T = D/2260 in SI (metric) units Where: T = Time, seconds D = Door width, inches (mm) W = Door weight, lbs. (kg) The values for “T” time have been rounded up to the nearest half second. These v
38、alues are based on a kinetic energy of 1.25 lbf-ft. 7 Table II Total Opening Time to 90 Degrees Backcheck at 70 degrees Backcheck at 80 degrees Backcheck at 60 degrees Table I plus 2 seconds Table I plus 1.5 seconds Table I plus 1 second If the door opens more than 90 degrees, it shall continue at t
39、he same rate as backcheck speed. Note: To determine maximum times from close to full open, the operator shall be adjusted as shown in the chart. Back check occurring at a point between positions in Table II shall use the lowest setting. For example, if the backcheck occurs at 75 degrees, the full op
40、en shall be the time shown in Table I plus 1.5 seconds. 6. SIGNAGE 6.1 Doors shall be equipped with signage visible from either side of the door, instructing the user as to the operation and function of the door. The signs shall be mounted 50” +/- 12” (1270 mm +/- 305 mm) from the floor to the cente
41、r line of the sign. The letters shall be 5/8 inch (16 mm) high minimum. 6.2 Consistent with section 2.2.1 of ANSI Z535.4 - 2002 the “signage and warnings“ guidelines of A156.19 are recognized, industry-specific standards that predate the adoption of Z535.4 and are not replaced by the standards set f
42、orth therein. 6.3 Power Assist Doors 6.3.1 When a separate wall switch is used to initiate power assist, the doors shall be provided with signs on both sides of the door with the message “EASY OPEN DOOR - ACTIVATE SWITCH THEN OPEN DOOR”.
